What happened to my static front page

Hi.
Tonight to celebrate a special event i made some updating to my site.
My target was to pubblish an artwork in the frontpage and redirict traffic to the usual frontpage layout creating another page similar to the usual static front page.
So i create a new page called “2nd Home Page” and i made the other changes, but starting from that point problems became to arise…
during editing of my frontpage the preview showed me the “2nd Home page”…
Thinking that problem arose from the title of that page i cleared “Home page” and i set the order of that page under my frontpage.

Even i erased my “2nd Home page” Page, that page result to be the front page of my site:
You can check it here.
